Please tell me, in formula hitech gen2, which as far as I understand is a reflection of the 1993 cars, the presence of DRS is indicated, is this some kind of error, or am I not understanding something?

The "DRS" button lowers the rear suspension to stall the underfloor and reduce drag.
It is in essence a real drag reduction system. It just works differently than in modern cars.

It was a real thing, it's not like, a mistake on the part of the developers, they just used a modern 'name' that was already in the game to refer to it - easier on the HUD and easier on the button menu.

I have had regular crashes that i didn't experience with the short testings i have done.
Switching to different Proton versions didn't help. So i decided to delete the whole config directory
and could drive about 15 minutes before quitting. So that might have helped.

I think, a lot has been said, it starts to become repetitive at this point and indeed drags along a bit. The vision of what is targeted is clear and potentially not to everyones liking (while i read stuff here that doesn't make sense for the direction some changes have taken, but doesn't matter).

Debating about how unrealistic sim A is vs. sim B isn't really wanted here. There are preferences on each side and it just leads to chaos at the end of the day.

For more discussions of that samey stuff (referencing outdated info already happened now, so we're not in the realm of 1.6.5 even) about your preferences in handling please try this thread, so this one here does not get hijacked by banging on the same topic in circles over 3 pages. Thanks!

So of the few car classes I have tried that have had tweaks to the tires, the GTE's seem the best by far. A much greater level of grip transitions can be felt with all the cars in this class vs others.

I am interested to know why this might be and if this level of feel can be obtained in other classes?

My guess would be that its not necessarily about the tires alone, but something else about the GTE's that allows a greater feel for the levels of grip that somehow the other classes don't translate as well.

LMP2 Gen2

I did about 50 laps in the Gen LMP2 and my very first impression - within one lap(!) - was "This is a GT3 with more aero!"
You race it IDENTICALLY in every single way! And the only difference is that it sticks to the road way better!

I started on the default setup (well I assume it loads up with default!) and raced off Eau Rouge flat out, not caring what happened as anything that DID happen would just be some data about its responses - sliding, crashing, or driving up through there fine....
But it had so much leeway to do Eau Rouge it was like a sunday drive! And then the rest of the lap was more or less too! Just by doing exactly as per GT3 - every single curb that is used, the same.. every corner you would do in the GT3 with 'super' rotation....
I have no idea what lap times are typical, but lap 1 was 2:10.... 2:09's within no time (2nd or 3rd lap).... starting with a full tank of fuel.... and very low 2:07 by the end of the run.

One big difference (to GT3) is the tire limit - the LMP2 has 'none'! It drives exactly like the GT3 BUT you never encounter a rear end loss - though maybe could if you really did something stupid! In 50 laps I never spun or crashed even once! Lovely aero!!! LOL

I did 'super' over-rotate once or twice early on on entry into a corner, but even that was super simple to deal with and correct it fine, so I changed the setup to Engine Braking 10 (I think it was) - but I am not even sure WHICH WAY is less or more! It seemed to be LESS.... but it wasn't a super extreme change for such a value change. It SEEMED to help reduce/erase that rear locking uder super rapid down-changing - but I will have to test more on that specifically as I ended up not deciding if it was THAT that helped or not.
Possibly some Differential settings would help too, but that was operating perfectly fine in all areas so I didn't even change a thing with that. Some cars (or sims) the Diff is as critical as anything else! And maybe the default setup had it just perfect for Spa anyway(?).

TC I ran6.. then 10... then 0.... as I did laps.... and like the GT3, no issue at all with any value used. And no lap time benefit for any either. Even with TC10 you could super rotate around Rivage. Though the ENTRY into Rivage is a bit different to be optimal. Deeper, under longer trail braking - a bit more typical of a real car.

It took a few laps to 'learn' the "No ABS" braking so as not to lock up the front(s) on it - pretty well only ever into the Bus Stop Chicane, but eventually not even there.

As for REALISM... well I have never driven such a 'high aero' car, so I can't truly know. Though you can EXTRAPOLATE if you have phyics/car/mechanical knowledge.....
Seeing it drives IDENTICALLY to the GT3 I would say that is WRONG!! Mostly because a high aero car would NOT LIKE 'angles' - you would lose aero fast then. So 'super rotating' could mean angled airflows = less aero effect. Probalby a reduction in rear end grip. But maybe it is not a lot of loss at LOWER angles, and also at those areas that have lower speeds.... and maybe I never surpass angles that truly matter(?). So I can only guesstimate results versus what SHOULD happen....
High aero cars tend to need to be driven 'linearly' for optimal lap times.

After a bit of setup changes it alway remained EASY to drive 'very fast' and maintain quite a lot of leeway per cornering area. eg Very low chance of error, and even if you did you could correct it to remain near optimal lap time anyway. Whether it was a front grip loss, or a rear grip loss.... though it is so 'easy' you rarely have any case of those anyway. Even if I was purposely a bit "push to the max and ignore a sensible, must stay on track, racing attitude" it was still easy to NOT error anything that mattered at all. Maybe up to 0.4secs on a bad error 'fix' - depending where that occurred.
Of course you could MAKE a crash , or slide off track, happen if you WANTED to.... but there is no point forcing that! Just race fast, hard, and see IF it happens.

I am sure it is nowhere near this easy to race a real LMP2 car around on its limits!
Though NEXT I have to find a high end lap time target to match.... as MAYBE it is so much faster than mine that it needs the car to be made 'dangerous' - But not basing it off ridiculous online world records etc - but general "Split 1" leader type times, which tend to be genuine and more realistic! (though not at al Alien level either! There is no need.)

I think I thought it was "fun" to race it around, but still always felt I was just racing another GT3 that had better aero..... oh, and no tire grip limit - seemingly just an incessantly progressive slide. (They SHOULD have a limit where they 'snap' - well most slick types/brands)

I think in a real car it is that you can feel, and measure, the G's (inertias)... even assigning WHERE they are headed... thus you just know how loaded up the rear (or front) tires are, and then how close to a limit they are. Via experience/memory-recorded, values you have learnt.
And if you have the ability to also APPEND all the dynamic factors that occur as you race around - such as a bump you know is "there", or curb hop you do "here", which will alter that grip loss point, then you have that very high accuracy that allows maximums to be run safely, all the time - versus the people who do not know all that and thus 'error' too often when they did NOT account for what was going to heppen due to the different case "X" they encounter this time.

Verdict: LMP2 is a GT3 chassis with a high aero body on it instead. LOL
Maybe they really are just that.....

-----
Oh.... top lap times of 2:04.5 region - at Alien level. So I am typically 1.0 to 1.5secs from that.. prob 1.5sec at Spa length...... which means the car needs to be made 'more dangerous', though it has a lot of leeway now so it should improve quite a bit and still be fine to drive. I had 'potential' of 2:06.5 with the car as it was, so I would be expecting/hoping sub 2:06 after serious setup investigation... (but who knows....)
I also doubt it will change the car's characteristics - it will just be more 'dangerous', capable of running over its limits easier.
Next time I will look up the lap time FIRST, sigh..... but I generally get within range on my own, before even knowing that record one.
2:07... not within acceptable range....

Please continue here for further physics discussion, the post has been moved and i ask everyone to follow up there:

Physic discussion thread

These long walls of text start to fill up this thread and don't really add much to the updates discussion.

Btw.: You state your disliking in a very stylistic manner with a lot of attitude, this feedback isn't really what i'd call being made in good faith, unless you think the "LOL" and constant caps emphasis does it any favour. I'm sure you'd reach more people by toning that down a little.

I'd like to share my opinion on the road effect, or the new shader. At least in VR, it now feels like the track is wet, even when it's not. I think it's due to reflections or specular light not sure exactly. I do like that we can see a "line" more clearly, but it still needs a bit of tweaking to give a more correct impression. (before was better in a "immersion perspective", now something looks off)

V1.6.5.1 just went live now - this is a hotfix to the latest update correcting the more pressing bugs intrroduced with it and also bringing a few further fixes and improvements to AMS2.

Some performance issues with AMD hardware have been addressed as have issues with flickering foliage and other minor visual oddities introduced with the latest shader updates; the game should also again launch fine from third party apps.

V1.6.5.1 CHANGELOG

GENERAL

Reduced the painted track detail offset to reduce overlap with vehicle tyres while still avoiding Z-fighting on large tracks

Reverted WIP development to aero flaps causing some existing cars equipped with DRS to malfunction

Reverted the damp track racing line visual changes which created some edge cases that caused the track to look too reflective

Fixed Shader causing flickering on Radeon GPUs.

Relaxed threshold for track limit violations in previous lap to invalidate the next lap in all non-TT game modes

UI & HUD

Fixed Test Day keyboard/controller menu navigation layout

Added graphics option to enable/disable LOD Fading (defaults to OFF)

Removed excess vertical padding from livery selection dialog (also prevents double activation when closing the dialog)

PHYSICS

Further minor adjustments to tread friction fade with velocity for all compounds to LMDh / GTP, LMP2 (both gens), P1 (both gens)

Adjusted GT Open carcass bend stiffness

Cadillac DPi: Minor center of gravity height & diffuser adjustments; Corrected fuel tank size being 1L oversized; Moved default brake bias slightly rearwards

GT1: Revised Nissan GT1 aero efficiency

Oreca 07 (All models): Corrected front camber adjustment range asymmetry (no setup reset required)

Metalmoro AJR Nissan V6: Corrected missing TC & ABS aids in authentic mode

AI

Adjusted AI downforce bias, peak slip angles, mechanical grip & AI lateral movement rates for better high speed stability & less erractic AI movements in F-Vintage, F-Retro, F-Classic, F-HiTech, Group C& GT3 classes

Further adjustments to AI lateral movement rates for F-Retro Gen1, F-Classics, GT3s

Sigma P1 G5: Reduced AI DRS drag scalar to mitigate risks of AI veering off track following front DRS activation

Adjusted AI dynamic corridors for Bathurst 1983, Silverstone 1975, Taruma Chicane

AUDIO

Fixed wall reflections and missing engine samples for Sigma P1 and Ginetta G58.

VEHICLES

GT3 Gen2: Added livery override support for yellow/white headlights; updated yellow headlights textures

F-Reiza: Minor adjustment to cockpit POV height

Just to be clear on this, does this mean just more drag or is downforce also increased in return?

Did something change with regards to MSAA in 1.6.5.1 compared to before? Because AA is way batter now and specular aliasing seems to have been significantly reduced. Was it broken before?
Using a Radeon RDNA2 GPU.

This was the tree flickering issue caused by the new LOD foliage introduced in 1.6.5 not MSAA related AFAIK.
Anti Aliasing looks better now in 1.6.5.1 than in 1.6.4

What is LOD fading doing? I would like to understand so that I can decide to better turn it on or off for me. Thanks.

As you get closer to trees and grass, the quality of the textures improves by loading new images with higher resolution. Rather than just using the new textures as soon as they have loaded, which can cause a jar in the rendering, it can now fade in to the new texture.
